Apple is poised to retain its dominance of the tablet market worldwide, and one leak of information after another is streaming out of Asia to reveal glimpses of what's next. Reports of more than one iPad model on the horizon are not new, however DigiTimes research indicates there could be three tiered models coming early this year.

The flagship model iPad 3 would be a high-end device featuring an updated screen with Retina-like resolution and top specs, including a next generation A6 mobile processor. A second tier A6-equipped iPad would feature the same insides however with a display matching the resolution of the iPad 2, which would reduce the price. Here's the kicker:

Looking for a deal on the iPad or iPad 2? Bargain hunters can rejoice now that Apple has slashed another $100 off the prices of selected refurbished iPads in the online store. Special limited time prices are the lowest yet, with a 64GB Wi-Fi only original iPad going for just $399.

That's a full $300 off the original retail price. Similarly, the Wi-Fi + 3G iPad with 32GB of storage is running $399, saving $330 off of the price at launch. For an extra $100, you can purchase a 64GB refurbished Wi-Fi + 3G iPad, putting the total at $499. Last year's iPad models aren't the only ones for sale at discount refurbished prices.

The possibility of an iPad 3 launch later this fall is not a new concept. Reports as early as February claimed Apple would try to get a jump on the competition by launching an iPad 3 before Christmas. More evidence has appeared that seems to corroborate this claim.

If the screenshots of Target inventory computers found by TiPb are real, then the massive retail chain has already discontinued the iPad 2. Retail associates speaking to the blog claim that none of the current iPad models are slated to be ordered by the company going forward.

I know how Sears feels. When I was younger I worked for a large retail store where people would regularly bring me expensive items and tell me they found them in a dump bin or on the discount shelf. A lot of them cited some fictional law that said I had to give them the discounted price. I spent many wasted hours of my life explaining why people couldn't buy a pair of $100 brand name sneakers for only $10.

Sears is facing a similar headache after they accidently listed the 16GB iPad 2 for $69 on their website. The retail store blamed a third party seller for the mistake, and informed people who bought the discounted device, that they wouldn't be honoring the false sale price after it went viral on Facebook and Twitter.

Shipping times for the iPad 2 are down to 1-2 weeks on the Apple Store online. This may better than 4-6 weeks for consumers, however the extended delays experienced since the iPad 2 was launched have caused analysts to reduce their Apple sales forecasts. IHS iSuppli now expects Apple to deliver 39.7 million units including all iPad models in 2011.

Their previous estimate was over nine percent higher at 43.7 million units. Other analysts aren't as optimistic. JPMorgan and Merrill Lynch both reduced their annual estimates slightly however the forecasts are much lower, coming in at 27.3 million and 26.4 million units respectively.

For those who have complained that the iPad is "just a toy" the latest retailer to carry Apple's tablet will bring a chuckle. Toys R Us has jumped on the bandwagon and now offers the iPad 2 at select stores nationwide, along with iPad cases and accessories. The complete list of Toys R Us stores carrying the iPad 2 is available online, however this is no guarantee that the product will be in stock.

Apple still lists a 2-3 week shipping time for the iPad 2 when purchased online in the Apple Store. Toys R Us joins retailers Best Buy, Radio Shack, Target and Walmart along with wireless carriers AT&T and Verizon in offering the tablet computer.

Radio Shack is the latest retailer to offer Apple's iPad 2 and launches the device today at 500 stores nationwide. Pricing will be identical to Apple and other retailers including Best Buy, Wal-Mart and Target. The company plans to announce which stores have the iPad 2 in stock online.

Those interested in purchasing an iPad 2 at Radio Shack can also call their local stores to see if the device is in stock. Supplies are limited and roughly 2,000 Radio Shack locations will not have the tablet initially. Apple just launched the iPad 2 internationally and lists shipping times of 3-4 weeks on the Apple Store online.

Verizon corporate stores have reduced prices on the Wi-Fi only first generation iPad, offering the 16GB iPad 1 for only $299.99. The news comes as AT&T continues to slash prices on the iPad 3G and has already sold out of the 32GB model online. Retailers are clearly trying to unload old inventory as iPad 2 supplies slowly increase across the country.

Verizon Wireless began offering the Wi-Fi only iPad along with a MiFi data bundle late last year. According to reports, no contract is required to take advantage of the new pricing, and the deal is available in corporate stores nationwide.

UPDATE: For the time being, the 16GB WiFi + 3G is back in stock at AT&T's online store, the 32GB remains sold out.

The AT&T Mobility online store has dropped prices again on the first-generation iPad 3G + Wi-Fi. The 32GB model already sold out, and now a 64GB iPad can be bought new for just $529 contract-free. This is a full $300 off the original price, a steep 36 percent discount for those who don't feel like doing the math.

Apple has not followed suit, holding prices at just $100 off the original selling price. AT&T is offering the 16GB iPad for $429, less than the Wi-Fi only model entry level pricing at launch. Refurbished iPads can be purchased from Apple for even less.

Apple is having a hard time keeping the iPad 2 in stock as lines continue to form outside of retail stores and shipping times for online orders are pushed back. Some Apple stores received additional shipments this morning, only to have them sell out in a matter of hours.

Shipping times for online orders of the iPad 2 on the Apple website have been extended to 4-5 weeks. In contrast, accessories such as the Digital AV Adapter and some colors of the Smart Cover ship in three days or less. Apple originally estimated shipping times of 3-5 days, however within hours of the launch on March 11 the company had revised times to 2-3 weeks.
